A bit of communism OK in government? It's addictive! (7)
I believe the answer is:
smoking
'addictive' is the definition.
Although both the answer and definition are adjectives, I cannot see how they can define each other.
'a bit of communism ok in government?' is the wordplay.
'a bit of' indicates a hidden word.
'SMOKING' is hidden within 'communism ok in government'.
'it's' is the link.
Can you help me to learn more?
(Other definitions for smoking that I've seen before include "Emitting a cloud of gas" , "Puffing a fag" , "Using tobacco" , "unhealthy habit" , "Having a cigarette" .)
